e8757a73e6 'luaV_execute' keeps local copy of program counter and hook mask, 
to avoid excessive access to globals.

2376eb6347 barrier for prototype's cache (with new gray list 'protogray' to keep 
prototypes to have their caches visited again) + constant 'MAXMISS'
 2017-05-04 10:32:01 -03:00
Roberto Ierusalimschy
8634b2a011 added 'cachemiss' field to prototype to avoid wasting time checking 
hits that fail too often

cb3d5dce30 opcodes 'OP_GETTABUP'/'OP_SETTABUP' operate only with string keys, 
so they can use fast-track table access

fd51651684 new macro 'vmfetch' to help changing code to computed goto's (macro 
abstracts the code to run before each instruction)

1a44e82200 'luaV_fastget' only treats the real fast case (table with a non-nil 
value at given key, so that it does not need to check metamethods)

9a5d6aedb7 trying to optimize a little 'luaD_poscall' 2015-11-13 11:24:26 -02:00
Roberto Ierusalimschy
04587b6256 macro with empty argument can be seen as macro with no argument; better 
to avoid that
 2015-11-12 16:08:58 -02:00
Roberto Ierusalimschy
ff1289a361 in 'luaD_call', use two functions instead of one with fixed boolean 
argument
 2015-11-02 16:48:07 -02:00
Roberto Ierusalimschy
c5363a1b58 in 'luaD_precall', in vararg functions, complete missing parameters 
only after moving them to final place (avoids checking the stack
again)
 2015-11-02 12:06:01 -02:00
Roberto Ierusalimschy
07a2dcacbf flag CIST_REENTRY changed to CIST_FRESH (its negation); fresh invocations 
seem to be less frequent than reentries. (So, avoid setting flag on
the frequent case.)

257961c601 OP_SELF can use 'luaV_fastget' specialized for strings, as it 
is applied only to string keys
 2015-10-28 12:50:09 -02:00
Roberto Ierusalimschy
8004ab756f hook test in 'luaV_execute' reduced to minimum (rest done in 
'luaG_traceexec'; no difference in performance for the non-hook
case, but keeps 'luaV_execute' a little simpler) + 'base' updates
replaced by 'Protect' (which serves this rule)

Roberto Ierusalimschy
b91bc93fd3 'setobj2t' incorporated into 'luaV_fastset' + 'invalidateTMcache' 
is not needed in the fast track (as it does not create new
entries)
 2015-09-09 10:44:07 -03:00
Roberto Ierusalimschy
41964648ee long strings are created directly in final position when possible 
(instead of using an auxiliar buffer to first create the string
and then allocate the final string and copy result there)
 2015-09-08 12:41:05 -03:00

a1415c0d72 bug in order NaN x int (tests must ensure that NaN does not get 
converted to integer)
 2015-06-09 12:53:35 -03:00
Roberto Ierusalimschy
ed1fe28bb8 When comparing integers with floats, use float as common type when 
possible (i.e., when integer fits in a float without losses); seems
to be more efficient in architectures with native support for used
Lua numbers

d39bb51faa bug: interpreter cannot pop activation frame before calling return 
hook (as it may want to access local variables active by the end
of the function)

6dc20ff293 'l <= r' for numbers has its own function, instead of using
